MILITARY SHOULDER-ARM..

I To all whom it may concern:

Be it known that I, THOMAS C. JOHNSON, y

a citizen of the United States, residing at New Haven, in the county ofV New I-Iaven and State of Connecticut, have invented a new and useful Improvement in Military Shoulder-Arms; and I do hereby declare the following, wheny taken in connection with the accompanying drawings and the characters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of and represent, in f Figure 1 a view partly in right hand side elevation, and partly in vertical section of the middlel portion of a military shoulderarm constructed in accordance with my invention. Fig. 2 a broken reverse plan view thereof. Fig. 3 a detached broken plan view of the rear end of the forestock. Fig. 4 a

plate. Fig. 5 a detached view in front elevation of the receiver-extension. Fig'. 6 a detached view in rear elevation of the forestock.

My invention relates to an improvement in military shoulder-arms, the ob]ect being to provide simple and reliable means for holding the forestock against forward displacement without imposing any strain upon the barrel, and with the minimum cutting of the forestock itself.

With these ends in view, my invention consists in a military shoulder-arm having certain details of construction as will be hereinafter described and pointed out in the claims. f

In carrying out my inventionY as herein shown, I employ a forestock tie-plate 2 having flat upper and lower faces and located in a central, longitudinal clearance groove or slot 3 having a at bottom wall and formed in the upper face of the rear end of the forestock 4, the forward end of the said plate being rounded as at 5 and formed with v a vertical, threaded hole 6 for the reception of a vertically arranged retaining-screw 7 extending upward through a bushing or es- Vcutcheon 8 inserted into a vertical shoul- Gopiesoi this patent may be Obtained for Specification of Letters Patent.

groove 3. By employing a tie-plate with a flat lower face instead of with a depending Vlocking-lug as heretofore proposed, I avoid cutting the forestock to receive the said lug the locking effect of which is in my present construction taken by the screw 7, which may be of anyrequired size to discharge this function.

At its rear end the tie-plate 2 is formed with a threaded shank 10 entering a thread-` Y extension 13 the rear face of which is formed with a threaded lug 19 for the reception of a screw 20 passing upward into it through the forward tang 21 of the box-magazine 2.2. If desired, the plate 2 might be formed integral with the receiver-extension, though the construction shown is preferred. So far as my present invention is concerned, the receiver-extension might be made integral with the receiver. The term receiver in the. claims is to be understood as covering the receiver whether its extension is integral or otherwise, except in those claims in which the receiver-extension is specifically. mentioned.

I claim Y 1. In a military shoulder-arm, the combination with the receiver thereof, of a forestock, a tie-plate extending forward from the receiver, connected therewith and having a flat lower face, and a vertically arranged screw passing upward through the forestock and into the said tie-plate.

2. In a military shoulder-arm, the combination with the receiver and receiver-extension thereof, of Va forestocl formed in the upper face of its rear end with a groove, a forestoclr tie-plate locatedin the said groove, connected at its rear end with the receiverextension and having a flat lower face, and a vertically arranged screw passing upward through the forestock into the said plate.
